Furnace noises that require professional repair

Between annual maintenance by a professional and routine DIY care and repair, a well-cared-for furnace can last up to 20 years and function properly. Many furnace repairs can be a quick and easy DIY fix, however not all repairs are so simple. If your furnace starts making noises beyond just humming contently, it may be the source of a more serious problem. If that is the case, you’ll want to call a professional right away and not attempt to repair it yourself.

Night “n” Day Home Services shares some furnace sounds to keep an ear out for, when it comes to calling in the professionals:

Loud bangs or popping

Smaller bangs and pops from your furnace are actually common and are usually the source of air ducts as they expand and contract. However, a louder sound, more like an explosive bang, could mean there is too much gas in the chamber. When the furnace is ignited, the excess gas creates the loud bang. This should never be ignored as it could lead to cracks and pressure on other parts of the furnace. Call a professional to check and repair things before it becomes both dangerous and expensive. 

Rattling or clanking

If you hear what sounds like metal clanking against metal, it may mean that there is a problem with the blower wheel. Turn off the furnace and call a professional for repairs. While this sound is certainly annoying, it may also eventually lead to more serious wear-and-tear on the system. Depending the state of the blower fan, whether it simply came loose or has completely fallen off, a professional will be able to quickly fix things or suggest an alternate solution.

Rattling noises on the other hand, may be something simple such as a loose screw. Try tightening the screws around the panel, but if that doesn’t fix the noise call a professional. A more serious problem may be a leak or crack in the heater exchange, which can lead to a carbon monoxide leak. Read more about symptoms of carbon monoxide poisoning.

Squealing or screeching

These two noises may be a number of different problems, so rather than trying to find the source yourself, it’s better to call a professional in. Things like damaged blower belts, dried parts, or a malfunctioning blower motor may all be the source of the problem. Rather than guessing though, a professional will be able to quickly pinpoint which is the cause. Likewise, if you hear a “thwapping” sound, it may mean something is stuck in the blades of the blower. Still call a professional to be safe, because even if it seems like a minor problem or sound inconvenience, it could lead to something more serious if ignored.
